Do I need an extra car battery for my audio system?
2900 (i assume meant) watts awful lot of power.
amplifiers using?
others have said, alt heart of electrical system. 10 batteries -- take long time deplete them, 90a alt go dead (at more 1/2 volume). 2nd battery nice, without big alt losing battle.
did find 1 160a alt pretty significant upgrade , cover unless plan blast non-stop: http://www.maniacelectricmotors.com/hiou...
overall car audio system have 2900 amps rms. largest battery can fit in car odyssey 1750. i'm not sure if sufficient run system or if battery or capacitors suggested.
